← In the circuit shown in the figure, inputs A and B are both connected to a NAND gate and to an OR gate. The outputs of these two gates are the inputs of an AND gate, whose output is Y. For every combination of A and B, the circuit behaves like a singleA simple pendulum has a time period T when it hangs in a lift at rest. The lift now moves with a constant downward acceleration, and the period of the pendulum becomes √2 T. Taking g = 10 m/s², the acceleration of the lift, in m/s², is ____. →
